FLUID SPRAYER Russian patent published in 2013 - IPC B05B1/26 B05B1/34 

FIELD: process engineering.

SUBSTANCE: invention relates to spraying of fluids and may be used in fire fighting, agriculture, etc. Hollow cylindrical sprayer casing has outer thread for distributing pipeline to be connected thereto for feed fluid and inner thread to connection to taper nozzle. Casing and nozzle make two aligned inner chambers. Cylindrical chamber serves for feeding fluid. Taper chamber formed by the surface of nozzle truncated cone makes pressure chamber. Nozzle has a jet arranged at side opposite fluid feed side and consists of cylindrical throttling orifice and tapered orifice with expansion directed toward the object. Thread is cut at taper orifice surface. At least, two rows of cylindrical throttling orifices are made at nozzle taper side surface. Axes of orifices are perpendicular to nozzle side surface. Each line has, at least, three throttling orifices. Projections of said orifices in horizontal plane are spaced apart by 7.5°-60°. Plate baffle is secured to nozzle end surface axially symmetric about aforesaid casing. Said baffle consists of, at least, two parallel plates arranged perpendicular to said casing. First plate is secured to nozzle end surface by, at least, three fasteners including screw, spacer shims arranged between the plate and nozzle end surface. First plate has central opening. Second plate is secured to first one by, at least, three fasteners including screw, spacer shims arranged between the plates.

EFFECT: higher efficiency of spraying.
